Title: Pneumatic transportation method for powder and granular material
Inventor: FUTAMURA KOJI
IPC: B65G53/12
Filed: 1992-02-07
Abstract: PURPOSE:To prevent contamination or breaking of powder and granular material and abrasion of a transport pipe by supplying the primary air to the inside of a transport tank quickly at the same time when the secondary air is supplied at the start of transportation, and stopping the primary air while the secondary air is still allowed to flow with leaving powder and granular material inside the transport tank to exhaust rapidly through an exhaust valve at the end of transportation. CONSTITUTION:At the start of transportation, the secondary air supply valve 12 is opened to supply the secondary air, and powder and granular material 5 situated at a lower exhaust port 3 is pushed out to a transport pipe 4. In this process, the primary air is supplied quickly by the primary air supply valve 11 until the pressure in a transport tank 5 reaches the predetermined pressure, and a stable and short plug is formed to perform transference to high concentration low speed transportation. At the end of transportation, the primary air is stopped with the secondary air left as it is and exhaust is carried out simultaneously from an exhaust valve 13 quickly under the condition that powder and granular material remains inside the transport tank so that transportation is finished under the condition in which the plug is cut off shortly. In this way, high speed blow-by of powder and granular material is prevented at the end of transportation.

When  a tape runs out in this state, an ASO lever 54 is turned, and the REW operator 12a is  held in the lock position. A gear 47 is rotated; and when its releasing piece 472 is disengaged from a pin 531 of an ASO driving lever 53, the ASO lever 54 is turned  counterclockwise and is returned to a position where it is brought into contact with an  engaging piece 552 of a switch slider 55. Therefore, holding of the REW operator 12a  due to an arm part 544 in the operation position is released, and the REW operator 12a is returned to the non-operation position, and the PLAY operator 12c is locked in  the operation position still, and a reproducing state is set, and the auto-play operation  is performed. Since the REW operator 12a is held in the operation position until the releasing piece 472 of the gear 47 is disengaged from the pin 531 of the lever 53, malfunctions are prevented surely.

Title: Heat transfer pipe
Inventor: CHIAKI TAKAO
IPC: F28F1/40
Filed: 1982-02-17
Abstract: PURPOSE:To enhance heat transfer performance and to save material for heat transfer  pipe, in a heat exchanger in an air conditioner and the like, by forming many grooves  having an approximately semicircular cross section in the outer surface of the heat  transfer pipe wherein fluid accompanying phase change flows. CONSTITUTION:Many semicircular grooves 3, which have a depth of (h), an arc angle  of 2Xtheta, and a radium ro, are formed in the inner surface of the heat transfer pipe.  When vapor is condensed on the heat transfer surface having the minute grooves, the  condensed liquid flows downward along the grooves 3. The faster the flow speed, the  thinner the liquid film. Thus the heat transfer performance is improved. Gravity of the  liquid, frictional force with respect to the wall, and surface tension act on the speed. A  size factor related to the driving force is a ratio between an equivalent hydraulic  radius, i.e. a cross sectional area of a flow, and a wetted perimeter. When this ratio is  large, the flow speed becomes fast, and the heat transfer performance is improved. In  order to make the equivalent radius large, the radius ro of a circle should be made  large. However, when the radius is made large, the number of the grooves is decreased  and the overall performance is decreased. Therefore the semicircular grooves with the  radius of ro which is close to the depth (h) of the groove are provided.

Title: Safety device of pneumatic static pressure spindle
Inventor: TANAKA HIROAKI
IPC: B24B47/14
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To reliably prevent the occurrence of a gall in a pneumatic static pressure bearing by metal contact by providing a starting torque restricting means to restrict stating torque generated by a motor to drive a main spindle in rotation to low torque of a no-load condition up to reaching command rotating speed from the beginning of starting. SOLUTION: When a work W advances too much to a position more forward than a work starting position, a thrust load is applied to the work W from a grinding wheel 17 in this position. When a work shaft 10 is started in this condition, since starting torque is restricted to a no-load condition by a torque restricting device 22, the work shaft 10 cannot actually rotate. On the other hand, when the thrust load acts on a pneumatic static pressure bearing of the work shaft 10 in a nonrotating condition, since a phenomenon such as a gall by metal contact is not caused, damage can be avoided.

Filed: 1985-02-09
Abstract: PURPOSE:To equalize the distribution of the dose of an electron beam from an electron-beam irradiation device by controlling the temperature distribution among several parallel linear cathodes when leading out the electron beam from the linear cathodes through a lead-out grid. CONSTITUTION:The electron beam irradiation device of this invention has a low-potential vacuum case 4, a negative high potential cylindrical shield 2 placed in the vacuum case 4 and several linear cathodes 1 installed inside the shield 2. An electron beam from the linear cathodes 1 is led out through a lead-out grid 3.

Besides, the degree of the opening of the grid 3 is partially controlled. Due to the above structure, the high distribution of the electron beam is reduced and the low distribution of the electron beam is increased, thereby equalizing the distribution of the dose of the electron beam.
